Abstract The spatiotemporal coherence of the edge-emitting broad-area laser diode was studied at different injection currents and optical path delays. Low observed in lateral direction laser, it further reduced to near zero by introducing an difference. A one-dimensional refractive element (ROE) designed fabricated destroy beam transverse direction. both directions when ROE introduced. Efficient two-dimensional speckle suppression achieved experiment using a microlens array ROE. freedom...
Purpose The purpose of this paper is to investigate the tribological effects laser surface texturing (LST) and residual stress on functional surfaces. Design/methodology/approach Three different textures (circular dimple, elliptical dimple groove) with two textured area ratios (10 20 per cent) are designed fabricated by a Picosecond Nd YAG Laser machine. friction wear performance specimens tested using UMT-2 testing machine in mixed lubrication. Findings Test results show that dimples...
Dense spectral beam combining (DSBC) of a laser diode module at wavelength 650 nm was realized for what we believe to be the first time. In this paper, optimal locking interval range band obtained by stimulation. A DSBC device containing 19 single emitters designed and built according interval. The output power reached 17.74 W, stable width 4.75 nm. quality factors (M 2 ) in fast-axis slow-axis directions were basically same as that emitter, even slightly optimized direction. brightness...
Abstract The spatial coherence of filaments in edge-emitting broad-area semiconductor lasers (BALs) is studied based on speckle theory, and a passive suppression method for BALs demonstrated. A fly-eye lens used to integrate the homogenize laser beam. contrast consistent with theoretical calculation, which proves incoherence filaments. light pipe introduce an optical path difference between different incident angles, enabling more incoherent beamlets. These beamlets are then combined at...
